Plutarch, Cato the Younger
Bernadotte Perrin, Ed.

34. But although they had in this way usurped the power, and although one part of the citizens was made submissive to them by gratitude and the other part by fear, nevertheless they were afraid of Cato. For even when they did prevail against him, it was with difficulty and toil and not without the shame of exposure that they forced their measures through at last, and this was annoying and vexatious to them. [2] Clodius, too, could not even hope to overthrow Cicero while Cato was at Rome, but since he was scheming for this above all else, when he had come into office he sent for Cato and made proposals to him. He said that he regarded Cato as the purest man of all the Romans, and that he was ready to prove this by his acts. Therefore, though many were soliciting the commission to Cyprus and the court of Ptolemy¹ and begging to be sent upon it, he thought Cato alone worthy of it, and therefore gladly offered him this favour. [3] But Cato cried out that the thing was a snare and an insult, not a favour, whereupon Clodius haughtily and contemptuously replied: ‘Well, then, if you don't think it a favour, you shall make the voyage as a punishment,’ and going at once before the people he got an edict passed sending Cato on the mission. Moreover, when Cato set out, Clodius gave him neither ship, soldier, nor assistant, except two clerks, of whom one was a thief and a rascal, and the other a client of Clodius. [4] And as if he had put a slight task upon him in the mission to Cyprus and Ptolemy, Clodius enjoined upon him besides the restoration of the exiles of Byzantium, being desirous that Cato should be out of his way as long as possible while he was tribune.
